Letters Patent No. 105,026, dated July 5, 1870.

The Schedule referred to in these Letters Patent and making pant of the same Hrw- To all whom it may concern 'Be it known that l, WILLIAM H. ANDREWS, of New Haven, in the county of N ew Haven and State of Connecticut, have invented a new Improvement in Reversible Latch; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part ot' this specification, aud represent, in

Figure' 1, a side view,

Figure 2, the salue, the plate removed,

' Figure 3, a section on line :1: x, and in Figure 4, a section ou line y y.

This invention relates to an improvement iu knoblatches, the object being to make the latch-bolt reversbl, to adapt the lock to a right or lett-hand door; an

The invention consists iu the arrangement'of afnut' upon the spindle of the latch-bolt, arranged so as to be operated through au aperture-in the case, substantially as set forth, combined with a yoke through which the latch is operated, so that by the turning of the said nut the latch maybe thrown out and set to any position, and then returned to the case.

A is the case.

B, the face-plate.

C, the latch-bolt.

D, the follower, of the usual form.

-E, the yoke, upon which the follower operates, formed with a head, F, through which the spindlea ot' the latch-bolt passes.'

The latch-bolt is threaded, and ektends through the head F, so as to receive a nut, I.

The nut I is held against the head F by a spiral or other suitable spring, G, so that the nut I binds the latch-boltto the follower, as seen in iig. 3, and yet so that, by turning the nut I to one screw from the spin- One great advantage of this construction. is that I- am enabled to make an extremely thin lock.

I do not wish to be understood as broadly claiming the attachment of the latch-bolt to the nut, as such is not new.

I-olaim as my invention- The combination of the latch-bolt O, with its spindie a., with the yoke or connection E, and nut I, the said nut arranged upon the spindle ofthe latch-bolt, and so as to be operated through an aperture in the case, to throw out or draw in thelatch-bolt, as the case may be, without opening the ease, in the manner substantially as herein set forth.-

WM. H. ANDREWS.
